Title: Process and apparatus for eliminating higher-boiling point impurities prior to rectification of a gas mixture
IPC: F25J3/08
Filed: 1950-05-11
Abstract: 673,492. Air separation. LINDE AIR PRODUCTS CO. May 11, 1950 [May 20, 1949], No. 11726/50. Class 8 (ii) The elimination of higher boiling point impurities such as carbon dioxide and hydrocarbons from a gas mixture e.g. air prior low temperature rectification in a column C, Fig. 1 comprises washing in a scrubber 15 a stream of cold dry mixture at a condensation pressure below 150 p.s.i. with a scrubber liquid which retains the impurities, and removing said impurities from the scrubber residue by passing the latter through an adsorbant e.g. silica gel, in one or other of chambers 64, 641 and thereafter recirculating the purified scrubber liquid through the column 15. For the production of gaseous oxygen, cold dry compressed air leaving nitrogen and oxygen regenerators 12, 13 by a duct 14 enters the base of the column 15 the top of which is supplied through a pipe 65 with scrubber liquid having traversed chamber 64 or 641. Scrubber liquid is also supplied through a valve 35 ; being obtained by passing clean air through a duct 31, cooling coils 32, 53 and ducts 33, 34. Clean air in a duct 36 is warmed in passages 56 by air tapped from the warm ends of the regenerators 12, 13 before being work expanded in a turbine 39 and passing to the low pressure column 21, the cooled tapped air passing to the column 15 to serve as make-up scrubbing liquid. Clean air also traverses a duct 16 where it is joined by liquid air from the duct 33 before passing to the high pressure column 17. Liquid oxygen from the base of column 21 is vapourized in a chamber 44 and traverses a duct 49, a heater 50, a duct 51, and one or other of the regenerators 13 to a delivery duct 52. In a modification the adsorption of dissolved impurities is effected in two stages and scrubber liquid from the first stage is returned to the scrubber column at a point below that at which purified scrubber liquid from the second stage is delivered. In a further modification wherein oxygen is run from the base of the low pressure column 21, Fig. 3, dry cold compressed air leaving one or other of final heat exchangers 80 through a valved duct 214, enters the base of a scrubber column 215, where it is washed by purified scrubber liquid returning from a chamber 264, and liquid overflowing into a cup 88 passes to a chamber 86 where it is further washed by purified scrubber liquid also returning from the chamber 264. Clean air from the chamber 215 is liquefied in a coil 232 and is fed through a duct 216 to the high pressure column 17 and clean air from the chamber 86 also passes to the column 17. The necessary extra cold is produced by expanding in an engine 83 a portion of air leaving the preliminary heat exchanger 212 and delivering it to the chamber 215. Filters 62, 262 for the removal of solid impurities may precede the adsorption chambers 64, 641, 264 in all three processes.

Abstract: 943,485. Electron beam apparatus. ZENITH RADIO CORPORATION. April 8, 1960 [April 10, 1959], No. 12646/60. Heading H1D. In a method of producing an electron beam that exhibits Brillonin flow, a beam of electrons is accelerated within, and parallel to, a magnetic field, and is first converged and then permitted to diverge before again being subjected to a gradually increasing convergent field until the beam attains a resultant crosssectional area at which the net radial forces acting on its electrons approach zero. As shown, all but a small proportion, e.g. 1%, of the electrons emitted by cathode 10 are intercepted by first anode 13. The potentials, relative to the cathode, of anodes 13, 15, 17, 18 are 8, 150, 15 and 7 volts respectively, so that the beam passing through anode 13 is converged to a minimum cross-section in the region of anode 15 and afterwards diverges until, after passing anode 17, it is again subjected to a convergent electrostatic lens system for aligning the beam envelope parallel with the tube axis. Two further anodes 32, 33 may be provided to intercept marginal electrons and accurately define the beam envelope. The electron gun may be used in a parametic amplifier, Fig. 3 (not shown), of the kind described in Specification 929,015.
